Hi Joelle:Just one O2 sensor, in you exhaust manifold or in the pipe between the manifold before the catalytic converter.Hope this helps; also keep in mind that your feedback
is important and
I`ll appreciate your time and consideration if you leave some

Thank you for using FixYa, have a nice day
This is in conection with my previous question.
The coolant system is a closed system. When the system is full the reservior acts as an expansion container. When the engine heats the coolant expands. The coolant expands into the reservior when the pressure cap releases. As the engine cools the coolant contracts and the radiator cap allows the coolant to flow back into the engine. If you are having coolant loss it should show as an external leak If there is no external leak it could be possible to have an internal leak. In theory this system should not lose anything but coolant loss on a small basis is expected. If your coolant loss is great and it is not seen externally I suggest that a pressure test involving engine components be done. I hope this can help Moe
93 civic. Turn key all instrument light ,
Bad ground. Check the battery terminals. The amount of juice required to turn over engine is not getting through, where as the radio draws much less juice. Also, once all connections are cleaned, positive & ground at the battery and fram and the hot at the starter (best to do prior to snow fall anyway), you should be good to go. If not, turn on the interior dome light and try to start it. If it doesn't start, have your battery tested. Finally, if all is good, you should have the alternator tested as well. Most auto parts stores will provide that for free!
Please provide feedback ratings

Overheating Honda
FIRST OFF,YOU NEED TO ASK YOURSELF,IS IT OVERHEATING OR COULD IT BE A FALSE READING ON THE DASH.JIM
Passed 25 mph emission test
When was your last tune up? I mean new plugs wires and distributer cap. have you had the throttle body cleaned if not that will need to be done as well. The cleaning is not hard or expensive but it cleans all the build up off the throttle body. Catylytic converter may also be plugged. What I would do before your test is to run the car, get it good and hot and run it down the highway while holding the gas pedal to the floor several times to get the old carbon burnt out of the exhaust system, this old carbon in the system can cause high PPM readings for the hydrocarbons. Which simply means your engine is either not getting hot enough to keep the build up cleaned out, or your not burning fuel effeciantly causing a build up. If your getting no trouble codes or lights then the chances of an electrical system malfunction are minimal. There is also the possiblity that your engine needs some valve work done if the fuel is not getting burnt properly but if you get it good and hot and run all the old carbon out of the system you have a good chance at passing the test.
